Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.


Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)


Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)


Bolt Pattern - Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Ask the Experts about this Dexter Axle Trailer Hubs and Drums

  • Recommendation For Extra Hub/Drum For Dexter 8-249 Hubs
    Dexter 8-249 hubs normally have inner bearings like Item # L68149 and outer bearings like Item # L44649. If these are your bearings (the size will be stamped on them) then it sounds like you need Trailer Hub and Drum Assembly Item # 84556UC3 by Dexter which also has 8-249 stamped on them. This hub and drum assembly fits a 5 on 5 bolt pattern. You may also need Trailer Hub and Drum Assembly Item # AKHD-555-35-K which fits a 5 on 5-1/2 bolt pattern. Be sure and check your bolt pattern...

  • Replacement Hub and Drum for a 2003 Starcraft Gemini Popup camper
    In order to determine the correct replacement bearings and hub you will need to pull the hubs completely off and either measure the spindles using a digital calipers like the # PTW80157. You can also remove the bearings from the hubs and check the numbers you find on the inner and outer bearing to determine which hubs would match the ones you're taking off. It's also good to know the capacity of the axle. The last thing you'll need to match is the bolt pattern on the hubs to your current...

  • Hub and Drum Assembly for 3,500 Pound Axle with 6 on 5-1/2 Bolt Pattern Hub Group 8-250
    The 8-250 hub and drum assemblies are unique in that they feature that 6 on 5-1/2 bolt pattern normally seen on higher capacity hubs. For a replacement you can use # 84656UC3. The bearings, races, and seal are included. You will also get a grease cap and new lug nuts with it. If your trailer has EZ lube axles with the grease fittings at the ends then you would need # 84656UC3-EZ instead. I have linked a couple of videos on these assemblies for you to check out.

  • Do I Need Brakes On Both Axles of a Car Hauler Trailer?
    In some situations, brakes can be installed on only one axle of a tandem axle trailer, however you should first check your state laws to see how many brakes are required for the gross vehicle weight rating (GVWR) of your tandem axle trailer. Some states require a specific number of brakes based on the maximum weight capacity of a trailer. If you are allowed to install brakes on only one axle, which axle you install them on depends on what type of axles you have on your trailer. If you...

  • Does 84556UC3 Come with 1 or 2 Hub and Drum Assemblies?
    The Dexter Trailer Hub and Drum Assembly # 84556UC3 is a single Hub and Drum assembly. We do not offer them sold in pairs, so you would need to purchase 2 individually if you're going to replace the parts on an entire axle. I've linked the installation video for this product to this answer. You could also go with the # AKHD-550-35-K , which is a more economical Hub and Drum assembly.

  • Replacement Hub Recommendation for Dexter Hub 8-250
    So I have your hub narrowed down to a few different possibilities but we need to know what your bolt pattern is to know for sure. We have the part # 84556UC3 for if your bolt pattern is 5 on 5 inch. We have the part # 845476UC3 for if your bolt pattern is 5 on 4-3/4 inch. Or, we have the part # 8-247-50UC3-EZ for the very popular bolt pattern of 5 on 4-1/2 inch. I attached an article that will help you identify your bolt pattern if you are unsure.

Most trailer wheels with a 5 on 5 inch bolt pattern have a center bore diameter of 3.19 inches, so you should not have trouble finding a wheel that will fit. We had this hub and drum assembly in stock, so I pulled it to get some additional information for you. As I stated, the bolt pattern is 5 on 5 inches.

  • How to Determine the Bolt Pattern of a Trailer Wheel or Hub
    There isn't a bolt pattern, at least not one used any more that I am aware of, that has a 2-7/8 inch measurement from bolt hole center to adjacent bolt hole center. Could it actually be 2-3/4 inches? If so that would indicate a 5 on 4-3/4 bolt pattern. A 5 on 4-3/4 inch is still rare. I have included a link to the options we have for hubs and for wheels. I have also included a link to a help article on how to determine bolt pattern.

    When measuring to determine the bolt pattern of a wheel with an odd number of lugs, like a 5 lug wheel, you are basically measuring the diameter of a circle that would run through the center of each lug hole. If you are measuring the wheel the easiest way is to measure the distance between the center of one lug hole to the center of the lug hole adjacent to it, then look on the chart and if that measurement is 2-5/8 inches the bolt pattern is 5 on 4-1/2. If it measures 3 inches the bolt...

    Usually a trailer axle will have a sticker or plate on it to indicate its weight rating. This may not be on the VIN sticker but it should be on at least one of your two axles. If not, contacting the manufacturer (Forest River, 574-264-4519) with the trailer VIN will let them determine what they installed initially. However, bear in mind that if the trailer has been in use for a really long time (as much as 14 years potentially) there is a chance that the original axle was replaced. If...

  • Can Magnet or Armature Surface of Wheel Hub/Drums Be Machined
    The surface of the brake drum where the brake pads contact can be machined, but the inside surface where the magnet rides, which is called the armature surface cannot. If the armature surface is grooved, discolored or pitted, you'll want to replace the hub/drum. If you'd care to reply with the reference numbers of your inner and outer wheel bearing, as well as the bolt pattern of your wheels, I'd be happy to make a recommendation for replacement hubs.

  • How to Add Surge Brakes to a Boat Trailer with Idler Hubs
    Since you have a brake mounting flange on your boat trailer you could pretty easily install brakes on the trailer. Most likely the mounting flange is a 4 bolt flange (all 4 bolt flanges are the same), since your trailer is most likely not too heavy if it didn't come with brakes. You should have no problem with the inner fender well either since they aren't currently interfering with your brake mounting flanges.
